Description

sshd-core and sshd-common fail to install inside karaf-4.2.1 container, as the following error is reported:

Uses constraint violation. Unable to resolve resource org.apache.sshd.core [org.apache.sshd.core/2.1.0] because it exports package 'org.apache.sshd.common' and is also exposed to it from resource org.apache.sshd.common [org.apache.sshd.common/2.1.0] via the following dependency chain:

  org.apache.sshd.core [org.apache.sshd.core/2.1.0]
    import: (&(osgi.wiring.package=org.apache.sshd.client.config.hosts)(version>=2.1.0)(!(version>=3.0.0)))

    export: osgi.wiring.package=org.apache.sshd.common

Until this is resolved I don't see how sshd-core is usable in OSGi.
